  • Excellent heater for garage
Size: 23,500 BTU Color: White
This heater puts out a ton of heat and is very simple to use. I would caution anyone buying this to keep the instructions manual and follow it very carefully, however all use and maintenance procedures are very simple. This thing works extremely well to heat my detached garage that is about 1,000 square feet. Used it the other night and it heated my entire garage from 40F to over 70F in about two hours. ... show more

  • Great helper during the winter season.
Size: 23,500 BTU Color: White
This heater is our winter savior! It doesn't just heat the room, but does it in a much faster manner, thus creating nice and comfortable leaving environment when it's most needed. We usually use this heater in order to boost up the heating procedure and, once the temperature has been reached the desirable level, we turn it off. That helps to save the level of oxygen in the room, to save the fuel and the electricity. Another good feature of this heater is that it moves the excess moisture form the leaving space. We leave near the ocean and, in winter time, severe fogs, strong winds and ocean mist get "into the bones". The heater makes the room warm and cozy. The wick should be serviced regularly, according to instruction. It really helps maintaining the flow of the flame - and the life of the filter itself. Some people comment on the kerosene odour, and it's, indeed, evident during the refilling and at the moments of igniting-warming-up and of the extinguishing the heater. But sometimes some regular cooking brings more fume than this device does. And it, as well as the smell of the kerosene, goes away with a brief room ventilation. I personally do not find the smell of the kerosene much offensive. It's, of course, my personal opinion. Once it's heated, there hardly any smell at all. The same goes with the intervals of no usage: the canister is quite well isolated. The electronic ignition works well only with the fresh, new wick. Otherwise the spark eventually stops reaching the wick. I have expected that form the start and found that, even after proper wick adjustment, the ignition isn't as reliable as with the new one. But igniting the heater with the match is no hassle at all. ... show more

  • It Works
Size: 23,500 BTU Color: White
Wanted a backup heater for ice storm threat. It arrived promptly and assembled average for such items. It heats but I need to point out that locating clear kerosene was difficult and over $5 per gallon. Concerns about red dye in the fuel complicated things. I spent about $200 for the preparation. Ice storm didn’t cause any issues. ... show more

  • Save on electricity
Size: 23,500 BTU Color: White
Wish I had bought one sooner! This product has great safety features, works well & is compact enough to work around. Quiet operation and excellent heat output. If I use it with temps over 30°F, it actually is too warm for comfort. On those nights in the teens, the entire front of the house is maintained at 69° with the bedrooms at optimal sleep temps! I saved so much on my electric bill this year! ... show more

  • Alternate heat source…CHECK
Size: 23,500 BTU Color: White
I purchased this kerosene heater because I did not have an alternate heat source when my power goes out. I’ve had this brand before and needed a new one. (SIMPLY FOLLOW ALL THE DIRECTIONS.)

  • OK but cheaply designed and built
Size: 23,500 BTU Color: White
Item packed great. Lousy instructions for assembling, also found the hardware cheap. Screws stripped out on the brackets that hold the wire safety cage to the heater. The 2 "C" Chinese made batteries were dead on arrival. The unit lit correctly 1 time, after that the glow plug is not working properly. All in all it produces good heat. I use it in a garage. I also am using the manual lighting method by using a long reach BIC BBQ lighter. To get the heater started you have to be pretty flexible and able to either sit on the floor or bend over to get too the controls. I am still looking for a new glow plug but cannot find one. I do not recommend this product unless you are up to playing with it. I do not recommend this for any senior citizens. ... show more
